Simple sample Class dc.Aclass [ Abstract ] { Index idxF On f; Property f As %Integer; } Class dc.test Extends (dc.Aclass, %Persistent) [ ClassType = persistent ] { ClassMethod Test() { k ^dc.testD,^dc.testI &sql(insert into dc.test(f) values(30)) &sql(insert into dc.test(f) values(303)) zw ^dc.testD,^dc.testI } } Output: USER>d ##class(dc.test).Test() ^dc.testD=2 ^dc.testD(1)=$lb("",30) ^dc.testD(2)=$lb("",303) ^dc.testI("idxF",30,1)="" ^dc.testI("idxF",303,2)=""
go to post Vitaliy Serdtsev · Apr 13, 2022 having the field defined as integer would allow selecting avg but running a query in my Zen page wouldn’t show me a time format If you the field is defined as %Integer or %String, then this is incorrect. The field type must be %Time. In this case, a time will be stored in the database as number, and the query will display the time as a string. Here is a small example: select 166 seconds,%external(cast(+166.5 as TIME)) "avg" Output: seconds = 166 avg = 00:02:46 Simple sample Class dc.test Extends %Persistent { Property t As %Time; ClassMethod Test() { d ..%KillExtent() &sql(insert into dc.test(t) values(30)) &sql(insert into dc.test(t) values(303)) zw ^dc.testD w ! s st=##class(%SQL.Statement).%New() s st.%SelectMode=2 d st.%ExecDirect(.st,"select t, %internal(t) tINT, %external(t) tSTR, avg(t) average,CAST(+avg(t) as TIME) avgSTR from dc.test").%Display() ; or w !! d ##class(%SQL.Statement).%ExecDirect(,"select t, %internal(t) tINT, %external(t) tSTR, avg(t) average,%external(CAST(+avg(t) as TIME)) avgSTR from dc.test").%Display() } } Output: USER>d ##class(dc.test).Test() ^dc.testD=2 ^dc.testD(1)=$lb("",30) ^dc.testD(2)=$lb("",303) t tINT tSTR average avgSTR 00:00:30 30 00:00:30 166.5 00:02:46 00:05:03 303 00:05:03 166.5 00:02:46 2 Rows(s) Affected t tINT tSTR average avgSTR 30 30 00:00:30 166.5 00:02:46 303 303 00:05:03 166.5 00:02:46 2 Rows(s) Affected

Therefore, if you have a field length >3.6E6, and there are several such fields, the limit is exceeded. To work around this, you need to change storage for your class. For example so: glbD(ID)=$LB(%%CLASSNAME) glbD(ID,"prop1")=prop1 glbD(ID,"prop2")=prop2 ... glbD(ID,"propN")=propN Simple example Class dc.test Extends %Persistent { Index mySimilarityIndex On SettingsJSON(KEYS) [ Data = SettingsJSON(ELEMENTS) ]; Index mySimilaritybackupIndex On SettingsJSONbackup(KEYS) [ Data = SettingsJSONbackup(ELEMENTS) ]; Property SettingsJSON As %Text(LANGUAGECLASS = "%Text.English", MAXLEN = 3600000, SIMILARITYINDEX = "mySimilarityIndex"); Property SettingsJSONbackup As %Text(LANGUAGECLASS = "%Text.English", MAXLEN = 3600000, SIMILARITYINDEX = "mySimilaritybackupIndex"); ClassMethod Test() { d ..%KillExtent() s json=$tr($j("",3600000)," ","0") &sql(insert into dc.test(SettingsJSON,SettingsJSONbackup) values(:json,:json)) w $l(json),":",SQLCODE } Storage Default { <Data name="backup"> <Attribute>SettingsJSONbackup</Attribute> <Structure>node</Structure> <Subscript>"SettingsJSONbackup"</Subscript> </Data> <Data name="json"> <Attribute>SettingsJSON</Attribute> <Structure>node</Structure> <Subscript>"SettingsJSON"</Subscript> </Data> <Data name="testDefaultData"> <Value name="1"> <Value>%%CLASSNAME</Value> </Value> </Data> <DataLocation>^dc.testD</DataLocation> <DefaultData>testDefaultData</DefaultData> <IdLocation>^dc.testD</IdLocation> <IndexLocation>^dc.testI</IndexLocation> <StreamLocation>^dc.testS</StreamLocation> <Type>%Library.CacheStorage</Type> } }

go to post Vitaliy Serdtsev · Apr 11, 2022 Any event that occurs outside of the modal group (such as a mouse click) automatically hides the modal groupproof. Use Popup windows with modal=yes or Dialogs. PS: if you really need to use "Model Groups", then you need to do two things for this: override the method onCanEndModalHandler override the method hideGroup(). This is necessary to prohibit the close button in the upper right corner Here is a small variant: Class dс.test Extends %ZEN.Component.page { XData Contents [ XMLNamespace = "http://www.intersystems.com/zen" ] { <page xmlns="http://www.intersystems.com/zen"> <button caption="Show modal group" onclick="zenPage.show();"/> <modalGroup id="mgStatic" groupTitle="Popup"> <text id="mgText" label="Value:" /> <button caption="OK" onclick="zenPage.mgBtnClick();"/> </modalGroup> </page> } ClientMethod show() [ Language = javascript ] { zenPage.__canClose = false; var mg = zen('mgStatic'); mg.onCanEndModalHandler = this.onCanEndModalHandler(); mg.hideGroup=this.hideGroup; mg.show(); } ClientMethod mgBtnClick() [ Language = javascript ] { zenPage.__canClose=true; zen('mgStatic').onCanEndModalHandler=null; zenAlert('User entered: ' + zen('mgText').getValue()); // hide the modal group zenPage.endModal(); } ClientMethod onCanEndModalHandler() [ Language = javascript ] { return true; } /// Hide the group.

go to post Vitaliy Serdtsev · Apr 7, 2022 Is it OK to use this partially rebuilt index if I don't care about data that isn't indexed? Did you do this before? I didn't build indexes manually, except for tests. If the index is not built for all data, then the query will see only the data for which the index exists. Try simple example: Class dc.test Extends %Persistent { Index iF On F; Property F As %Integer; ClassMethod Fill(N = 10) { k ^dc.testD,^dc.testI s ^dc.testD=4 s ^dc.testD(1)=$lb("",22) s ^dc.testD(2)=$lb("",11) s ^dc.testD(3)=$lb("",44) s ^dc.testD(4)=$lb("",33) d $system.SQL.TuneTable($classname(),$$$YES) d $system.OBJ.Compile($classname(),"cu-d") k ^dc.testI d ##class(%SQL.Statement).%ExecDirect(,"select * from dc.test").%Display() s ^dc.testI("iF",1,22)="" w !! d ##class(%SQL.Statement).%ExecDirect(,"select * from dc.test").%Display() s ^dc.testI("iF",4,33)="" w !! d ##class(%SQL.Statement).%ExecDirect(,"select * from dc.test").%Display() } }
